Application filed April 5, 1889. Serial No. 306,132. (No model.)

To all whom it may concern.-

Be it known that I, BRISBANE MARSHAL TURNBULL, a citizen of the UnitedStates, residing at Scranton, in the county of Jackson and State ofMississippi, have invented certain new and useful Improvements inVentilators; and I do declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same.

This invention has relation to improvements in devices for ventilatingrailwaycars and collecting and removing dust from the air admitted; andthe novelty will be fully understood from the following description andclaim, taken in connection with the annexed drawings, in which- Figure 1is a side view of a portion of my improved device removed from the car.

Fig. 2 is a front view of the entranceportion. Fig. 3 is an interiorview of the main pipe, showing the circularly-arranged brush therein.Fig. at is an end view of a car with my improvements applied. Fig. 5 isa view of the railway car, showing my improvements in side elevationtherein. Fig. 6 is a view of one of the screens removed from the car.Fig. 7 is a detail view of one of the lags 0 or brushes which I employon the inner side of the screen. Fig. 8 is a side elevation of one ofthe brushes. Fig. 9 is a View of one of the brushes and screens inposition, and Fig. 10 is a similar view.

3 5 Referring by letter to the said drawings, E

indicates a pipe, which is provided with numerous perforations and hasat opposite ends a downwardly-directed branch O, which is designed toextend a sufficient distance down the end walls of a car, on the innerside thereof, and carry at their lower ends a removable cap F. The pipeE, which is a continuation of the branch of 0, assumes a position on theinner side of the car, and preferably along the ceiling.

A indicates an entrance, which is of a flaring form. This flaringentrance communicates with the vertical branches O of the pipe, and hasa screen B at its contracted portion or point of communication with thesaid pipe O, the flaring mouth or entrance portion A being arranged uponthe outerside of the end walls of the car, so as to collect the air oratmosphere during the travel of the train. 5 5

D indicates a brush,which may be of wire, hair, or other suitablematerial. This brush is arranged within the vertical branches O of thepipe at a sufficient point above the flaring mouth or entrance, and isdesigned to remove cinders and other impurities, which drop to thebottom of the said branch O, and may be removed by taking off the cap F.With a device of this construction a car or train of cars mays bethoroughly ventilated by the admission of pure air, and foul and impureair which arises in the car carried oif and discharged by suctionthrough the perforations in the pipe E.

P indicates ascreen,which I arrange in the end wall of a car on the sideopposite my ventilating device. This screen is backed by brushes L, sothat any impurities which may enter the screen will be checked by thebrushes, the screen being held in a suitable 7 5 frame K.

From the foregoing description, taken in connection with the annexeddrawings, the operation and advantages of my invention will be obvious.

Having described my invention, what I claim is- The car-ventilatorconsisting of a perforated pipe extending from end to end of the car andhaving a downward iinperforated extension at each end thereof, saidextensions being each provided with a brush therein, a removable cap atthe open end thereof, and a flaring air-collector located between thebrush and the cap and provided with a screw, 0 substantially asspecified.
